去除Visual Paradigm输出图片中的浮水印

BoUML都收费了，argoUML半年没更新了，而startUML六年多没更新了，免费的UML工具里就数VP的社区版还不错了。唯一的缺憾就是输出图片有浮水印，虽说咱们也四处宣传VP，但输出的图片实在不方便。VP 9已经将浮水印贴满整个背景，影响导出图片的可读性。

 

不过，SVG导出功能还在！(这是我唯一还在坚持VP的理由!) 我写了一段脚本，帮助去除VP输出SVG图片中的浮水印，并转成PNG。这个PNG转换的功能依赖于Inkscape，没有的话去SourceForge.net下吧。 注意安装后要把Inkscape的安装路径放在PATH中去。

Inkscape支持命令行，如下:

  inkscape -f srcSVGFile -e tgtPNGFile -d 150  (d后面的dpi值，150基本可以适用于放到PPT讲解用了. 其它参数用--help就可以看了)

 

脚本也简单，就是把SVG文件的某个特定的浮水印字符去除，然后呼叫inkscape转换下就可以了。支持单个文件转换或者一个目录下所有文件转换，还算方便吧。
